Abstract: 824,159. Cold separation of air. UNION CARBIDE CORPORATION. March 7, 1958 [March 22, 1957], No. 7460/58. Class 8(2). In a rectification process wherein air having a compressor 10 at less than 150 p.s.i. is cooled, and freed of readily condensible impurities in heat exchanger with returning nitrogen e.g. in alternating exchangers 12 and in a scrubber 20, part of the so cleaned air in a duct 22 is warmed in heat exchangers 23, 28 recompressed to above 2000 p.s.i. in a compressor 31 and is then divided into a first portion which is cooled in passage 25 of exchanger 23 and expanded at a valve 34 to less than 150 p.s.i. after which it is joined by the remaining high pressure air after being cooled by an external refrigerant e.g. ammonia in an exchanger 35 and expanded with external work at 40 to below 150 p.s.i. ; the so combined air streams then passing to a conventional double column 51, 53. Liquid and gaseous oxygen products are drawn from the low pressure column 51 through valved ducts 65, 87 respectively and crude liquid nitrogen is drawn from the high pressure column 53 through a valved duct 89. To provide the necessary flow unbalance for regenerators 12 a minor portion of the low pressure air by-passes the regenerators and is further compressed at 69 to 2000 p.s.i. cooled in exchanger passage 29 and in an ammonia refrigerator 73 and added to the cold high pressure air leaving the exchanger 35. In a modification the scrubber is replaced by an adsorption trap and the whole of the incoming air is cooled in an indirect countercurrent heat exchanger having a non- reversing passage traversed by a portion of the cold air leaving the absorption trap.

Patent GB-1013808-A (GB)
Abstract: 1,013,808. Controlling and propelling aircraft &c. ELECTRO HYDRAULICS Ltd. May 21, 1964 [May 21, 1963], No. 20155/63. Heading B7G. [Also in Division G1] Displacement of a control member (Pilot Control, Fig. 1) causes corresponding displacement of two independently movable members (e.g. aeroplane flaps operated by a Master Jack and a Slave Jack), any positional difference between Master and Control producing a first error signal which operates a polarized relay 25 to drive the Master in the appropriate direction, and any positional difference between Slave and Master producing a second error signal which operates a polarized relay 33 to drive the Slave in the appropriate direction; the drive arrangement being such (Fig. 2) that if both errors occur at the same time, due to the Slave leading or lagging the Master while both are still responding to a control signal, the leading member is held stationary until the lagging member has caught up with it. The position sensors are potentiometers 22, 19, Fig. 1, providing the first error signal, and 20, 21 providing the second. The Master and Slave members may be operated by hydraulic jacks 1, 2, Fig. 2, and associated solenoids 15, 16 and 17, 18. The final error signal has one polarity when the Master jack is required to drive its flap upward, and the relay 25 (Fig. 1) then energizes relay 29, Fig. 1, and has the opposite polarity when a downward movement is required, thereby energizing relay 30. Similarly, for opposite polarities of the second error signal the " Slave up " relay 37 or " Slave down " relay 38 is energized. The contacts of the relays 29, 30, 37 and 38 are arranged, Fig. 2, so that, for example, when a " Master up " control is given, relay 29 operates and a positive potential is applied via contacts 29a to line 39. This potential is applied via contacts 29b to the " Master up " solenoid 15, and via the normally closed contacts 38b and 30c to the " Slave up " solenoid 17. If the Slave member lags or leads, either relay 37 or relay 38 operates to break either the Master solenoid circuit at 37b or the Slave solenoid circuit at 38b, to prevent movement of the leading member until the lagging member has caught up, when the said relay 37 or 38 will de-energize and both members will again follow the control signal. The circuit operates similarly if a " Master down " signal is given; and if no control signal is given but a positional difference arises between Master and Slave, due for example to unequal loading, then the appropriate relay 37 or 38 operates to connect a positive potential from the " a " contact of the operated relay (37 or 38) via the " b " contact of the unoperated relay to operate the appropriate solenoid 17 or 18. Failure of the synchronizing system may be detected and used to operate a warning, to disable the circuits, or to exchange a duplicate circuit for a faulty one.

Abstract: 1,143,549. Measuring flow-rates electrically. CHARBONNAGES DE FRANCE. March 17, 1966 [March 19, 1965], No.11797/66. Heading G1N. In a hot-wire anemometer, suitable for measuring the speed of flow of a gas laden with dust, an electromagnet is provided to produce a mechanical shock to free the detector filament from dust prior to taking a measurement. In the embodiment of Fig.3a, two platinum detector filaments D 1 , D 2  occupy respective perpendicular diameters of a gas flow duct 21 and an electromagnet 3 is arranged, when energized, to cause a rod 31 to strike the detector filament mounting 12. Two reference filaments (C 1 , C 2 ), similar to the detector filaments, are housed in a cavity 14 filled with stationary gas. The two detector filaments are connected in opposite arms of a Wheatstone bridge circuit, Fig.1a (not shown), the other arms being constituted by the reference filaments. The bridge is connected in series with the electromagnet coil (B) and a switch (I), to a D.C. source and the output voltage is fed via a switch (I 2 ) to an electronic recorder, possibly through a voltagefrequency coding device. A circuit incorporating a thyristor (Th) and R and C components for automatically short-circuiting coil B after a time delay after switch I, is closed and before switch I 2  is closed for taking a measurement is described with reference to Fig.4 (not shown). Alternatively, the electromagnet may be energized from a separate supply, Fig. 1b (not shown) in which case the bridge may be continuously energized. Only one detector filament and reference filament may be provided (Figs. 1b, 4). For high speeds of flow, the diameter of the gas inlet may be reduced by a plug (6) Fig. 7 (not shown). A modified form of casing (3) is described with reference to Fig. 9 (not shown) for connection to flexible piping for use as a flocometer. It is stated that the invention is suitable for use as a ventilation indicator in a mine.

A rocket for line-throwing comprises a chamber 7 in which is provided a propellant in the form of a plurality of compositions arranged one after the other in the intended burning direction, the compositions having different burning speeds and being arranged so that the composition with the lowest burning speed is nearest the thrust nozzle 8 and that the burning speeds of the compositions increase with increasing distance from the nozzle. The propellant may be a single block having varying compositions or may comprise a plurality of separate component blocks 1, 2, 3, 4, and 5. The burning speeds of the compositions contained in the blocks is approximately in the ratio 1 : 2 : 3 : 4 : 5 and their lengths are in the proportions 4 : 4 : 3 : 4 : 5, thus giving burning times of 4 seconds for block 1, 2 seconds for block 2, almost one second for block 3, and about one second each for the two remaining blocks, with thrusts of 5, 10, 15, 20, and 25kp, respectively. This produces substantially constant acceleration of a rocket to which a line is attached. Insulation 6 prevents combustion other than on the burning face of the propellant.
